End of the 15th century
At the end of the 15th century, the emergence of the idea that Moscow is truly a new Rome can be found;
the whole idea of Moscow as third Rome could be traced as early as 1492, when
Metropolitan of Moscow Zosimus expressed it.
Metropolitan Zosima, in a foreword to his work of 1492 ''Presentation of the
Paschalion'' (),
quite clearly expressed it, calling
Ivan III "the new Tsar
Constantine of the new
city of Constantine — Moscow."
This idea is best known in the presentation of the monk
Philotheus of the early 16th century:
The Moscow scholars explained the fall of Constantinople as the
divine punishment for the
sin

Ivan III), and therefore according to them the center of the Eastern Orthodox Church should have been located in Moscow, and thus the bishop of Moscow should become the head of the Orthodoxy.
The text of the bishop's oath in Muscovy, edited in 1505–1511, condemned the ordination of metropolitans in Constantinople, calling it "the ordination in the area of godless
Turks, by the pagan ''tsar''."

Orthodox faith was central to Byzantine notions of their identity and what distinguished them from "barbarians". As the preeminent Orthodox nation following the Byzantine collapse, Moscow would view itself as the empire's logical successor:
"The
